Vulcanus Studytour 2013

Preface This travel report is the closure of a highly successful Vulcanus Study Tour (VST). On the early morning of monday the 8th of July a group of 12 Vulcanus members gathered at the faculty of 3ME to start our annual foreign excursion. This year we were heading for Northern Germany to visit companies and research facilities in Hamburg, Papenburg, Bremen and Rendsburg. Everybody was looking forward to see and learn from leading companies in the marine industry and scientific community. Every year Master society Vulcanus organizes an international study tour to companies in our field of study. The maritime sector is a global industry although we focus mainly on the companies within the European Union. The Vulcanus Study Tour is intended to show the students of Marine Engineering and Mechanical Systems and Integration what they can expect after they finish their studies and put the work in an international perspective. The study tour is also a great opportunity to expand the professional network of our members and those we get in contact with. First of all I would like to thank the treasurer, Ewout Slachter, for his hard work this year in helping to organize the VST, although we had different titles assigned to us it was truly a shared effort. Secondly, I would like to thank the companies that welcomed us this year; we very much appreciated their hospitality and were treated to very interesting presentations and factory tours. Thirdly, I would like to thank ir. Klaas Visser and ir. Milinko Godjevac for their support this year and for joining us on the VST. And last, but definitely not least, I would like to thank our sponsors. Without their contribution it was not possible to organize and finance the VST 2013. I hope reading this year’s travel report will bring back good memories and motivate the new Vulcanus board and participating students to go beyond this year’s study tour. Enjoy the impression and I look forward to next year’s study tour. Although this year ended with a very enjoying study tour, for most of us this year will be marked by the tragic shock of Hugo Grimmelius’ sudden departure from life on the 12th of September 2012. He was a driving force in the 3ME faculty and made our study department into what it is today. He also was a proud member of the Vulcanus board, where he served in the function of treasurer from ’91 up until ’96. He kept a close relation with Vulcanus after this period by helping boards to organize excursions and company visits. And when we did go on our yearly VST he always joined, not just on the excursions but also at night to the bars, where he frequently went home with the last group of students. His absence could be felt throughout the year and on the VST, fortunately his active live has left us with many fond memories making sure he will be missed but not be forgotten.

Best regards, Mike Loonstijn Chairman Dispuut Vulcanus

Monday: Travelling to Germany At the start of the Vulcanus Study Tour 2013 we all assembled, properly suited up, outside the faculty in the nice weather that would keep with us for the entire studytour. The board had rented a highly efficient turbocharged diesel powered van to transport a part of the group to the first excursion location while the rest Ioana who kindly offered to take some students in her car.

After introductions were made the long drive began to the Meyer Werft in Papenburg (~300 km.) Because the tour takes place in the week after the exams and we all had to be up very early some students tried to catch up on some sleep.

Meanwhile the traffic was light, the sky was blue and the sun was out. This did reveal a problem with cooling the van’s interior. It turned out the airconditioning vents were only placed at the front of the van. Soon the first of the requests for more cooling air came from the back of the van which will be a much heard sentence throughout the studytour. Just before the complaints of frozen feet from the driver.

After the first kilometres of German Autbahn we arrived at Papenburg according to the Delft tradition, i.e. ‘fashionably late’.

Monday: Meyer Werft On our way to Hamburg the first important stop was in Papenburg. Soon the buildings of Meyer Werft rose from the peaceful landscape because of its size. 504 Meters long and around 100 meters high the shipyard wasn’t very hard to find. Meyer Werft calls itself one of the world leaders in building high end cruise ships. I must say, that’s something you immediately believe if you have been there.

After the general company presentation and some kindly provided sandwiches and drinks it was time to have the field trip we were looking forward to. But only after putting on some safety equipment of course. Wearing a hardhat is always a prologue to something cool.

The fieldtrip started at the sheet production line. To build the blocks for a massive ship you first have to build the sheets to make the blocks from. This starts by cutting portholes and access holes from separate sheets. Then these sheets are welded together and stiffeners are added. All welding is done using a cutting edge technique. Remember steel plates for these ship sizes are also very thick making the process even more amazing.

The next enormous building there was a block manufacturing and assembling street. As seen as in the automobile industry, blocks were assembled at a production street containing 12 stages. After 4 hours all blocks move one stage further on a huge conveyor rail. Every stage had its own particular handlings. Passenger cabins were already prefabricated, pipes and fittings are delivered to this street precisely on time because these pipes were already made by the big pipefitting area as seen earlier. One can only imagine and admire the supply chain management behind this work.

After witnessing the block manufacturing we entered the biggest building (504m) for the final assembly. Blocks have to be welded together to form a new luxury liner, final parts and machinery is installed and the hull has to be coated. This is a lot of work of course. This all is done in a big drydock which is also partly floodable.

During this visit one thought passed continuously through my mind: what fully grown up industry and a technology is this. More and more work is contracted out to low labour cost countries. But looking at the filled orderbook of Meyer Werft low it seems high- tech and efficiency still puts up a fight. I would like to end this report by expressing my appreciation to our tourguide of the day. Although being a last-minute substitute she was able to pass on her enthousiasm for the company and answer all the questions the group of current and future engineers could throw at her.

Tuesday: HSVA (Hamburgische Schiftsbau-Versuchsanstalt) After everybody had tasted the first night in Hamburg and slept well, we went in the morning of the second day (9th July) of the Vulcanus study tour 2013 to the Hamburgische Shiffbau-Versuchanstalt (HSVA.) This is the Hamburg Ship Basin. After a warm welcome, we looked at a demonstration film in which the history and today’s projects were visualized. HSVA will be celebrating her 100th anniversary the 10th of September this year. HSVA was founded in 1913 as a private and independent Ship Model Basin in Hamburg. In 1929 a tank of 320 m in length and in 1943 a large cavitation tunnel were taken in operation. Today HSVA is a modern ship model basin with an ice tank which is in daily use to do tests at all kinds of projects, vessels or offshore platforms that will sail in arctic environments. Besides the modern ice tank, HSVA has a side wave generator of 40 m in the large towing tank.

After the presentation we went for a tour to the cavitation tunnel, ships model construction area, big towing tank and the ice tank.

The cavitation tunnel was impressive. Complete ship models up to 11 m with attached propeller can be placed in the tunnel and all kinds of tests were done here. This includes cavitation tests at the propeller and rudder but also noise measurements can be performed. A model test will take mostly 1 week for mounting, testing and dismounting the model. The impeller with a power of 1700 kW can take up the velocity to 12,6 m/s. Provided the Hamburg power grid is up to it.

In the big towing tank there is also a 40 m side wave maker installed at half of the tank length. This is special for keeping the running times as efficient as possible. The wave maker can generate waves of 0,50 m height and a wavelength of 20 m.

The large ice tank is 78 m long and 10 m width. During our visit the employees were just preparing the tank to do tests at an offshore platform for Total. Lucky for us we were allowed to take a quick look in the towing hall. A quick look and a picture was just long enough because it was freezing cold inside, minus 20 degrees. Brrrrrrr

After the ice tank the tour was at its end. In the main entrance hall we thanked our guide by giving her a nice bottle of good old Dutch gin, the traditional Vulcanus necktie and said goodbye. Thank you HSVA for the nice and interesting company visit!

Tuesday: MAN Diesel and Turbo On Tuesday afternoon we went to visit a facility of MAN Primeserv in Hamburg. This is the largest Primeserv location in the world so the promise of an interesting afternoon was there. It was a sunny afternoon and we were greeted outside by Mr. Bunde, who was going to show us around.

We started our visit with a lunch at the company canteen, where we were treated to a hearty German meal of schnitzels and potatoes. After the lunch, Mr Bunde treated us to a presentation of several aspects of the MAN group, their operations and current developments in the industry. It was a very nice beginning to a knowledgeable afternoon.

Our group was very interested in all the new developments and current issues in the field of marine diesel engines. Luckily Mr Bunde was a former senior employee with a lot of knowledge of the company and their technology. This was backed up by his years of practical experience within the company with the stories of old to tell. He had several presentations for our group and even though we had already been in the canteen for over an hour, we were still hanging on his lips.

After the presentations we were taken on a tour to see the factory grounds. The Primeserv branch of MAN does not build new engines but rather services and overhauls existing engines. Inside the factory multiple different toolings were used to repair damaged parts of the engine. This ranged from large con- and eccentric lathes for crankshaft repairs to large mills for damaged pistons and cylinder heads. The nice thing about this tour was that Mr Bunde tried to involve the group into the different

VST2013 Page 12

Vulcanus Studytour 2013 techniques and parts by asking them questions on how they would be used in practice. This kept the students on their toes and involved with the tour.

When we finished the factory tour we got some coffee in the canteen and some of our members wanted more information on particular subjects. We got treated to some more presentations on these subjects until we were forced to leave because of a dinner reservation. All in all, we really enjoyed this visit and a special thanks to Mr Bunde who was kind, knowledgeable and a joy to converse with.

Tuesday: Dinner at Hoffbraeuhaus

On the second day of our tour we had arranged to have our dinner at the famous Hofbräuhaus which has a great history since 1589, when it was founded. Their very first brewery and beer hall is placed in Munich, but they have expanded in more cities in Germany like Hamburg and also worldwide.

During the dinner we had the honor to have with us Patricia van der Werf, deputy representative of the Netherlands Support Business Office (NBSO) in Hamburg. We invited her for dinner to thank her and show our gratitude since she was very helpful to reach some of her contacts and organize one of our company visits.

Also, as it was a dinner at a traditional German restaurant we did not miss the chance to have our beer in the large glasses or else "Muss" and ate some delicious sausages and pretzels.

This evening we thoroughly enjoyed ourselves and made new friends as there was also a group of Japanese electrical engineers in the restaurant having their dinner too. After a couple of rounds of beers going back and forth between their group and the Vulcanus members a shirt was exchanged. So Vulcanus is now known in Japan.

Wednesday: Nobiskrug After our second night in Hamburg where most of us once again discovered the beautiful night life of the Reeperbahn we went in the morning to the 4th company, luxury yachtbuilder Nobiskrug.

Unfortunately the German beers of the night before had an effect on our navigator and a not very small detour which took us via the Kieler Straße in Hamburg we finally arrived at the Kieler Straße in Rendsburg where Nobiskrug is located.

Once again we were very warmly welcomed, and after some coffee and cakes a company presentation was given. The company was founded in 1905 and has built all kinds of vessels since then. Their focus however shifted in the 21st century to mega yachts starting from 60m in length. The facility in Rendsburg has more than 400 employees which work either in the main office or elsewhere on the facility of 173000m².

After the presentation and questions, where after a technical question even a member of that specific area came to answer the question, we were given a tour over the facility. We were guided over the spread out facility and saw the plate cutting and welding facility, pipe fitting workshop and of course one of the dry docks (Nobiskrug has one drydock of 153m and another of 193 meters) where we witnessed their latest mega yacht Odessa II which was in her final stages of completion. Unfortunately but fully understandable we could not go inside to witness her luxury. We did see the part of the ship you otherwise never see, namely the bottom of the hull. Here the group was inspired to ask many engineering questions and the employees of Nobiskrug provided the group with a detailed insight of the industry.

I hereby like to thank Nobiskrug for their hospitality in showing us around and answering our questions. We were particularly impressed with your passion and drive to answer all our questions. This became especially clear when the junior engineer who joined us on the factory tour suddenly went missing, only to turn up minutes later after he informed at his supervisor about some of our questions he was unable to answer during the tour.

I had a very nice time and I’m impressed by your German ‘Craftmanship’ Furthermore I like to thank the sponsors for their financial participation and thereby allowing us to have the study trip in the first place.

Wednesday: International Maritime Museum Hamburg On Wednesday afternoon a part of the group went to the maritime museum which is located in the Speicherstadt (city of warehouses) in the old port of Hamburg. This part of the city is the largest limber-pile founded warehouse district in the world. The buildings in this district, as well as the maritime museum, are built around the year 1900. These buildings are special because most old buildings were destroyed in the extreme heavy bombing of Hamburg in 1943, also known as “the firestorm of Hamburg”.

The museum exhibits the private collection of Peter Tamm, which consist of 40.000 items and over one million photographs. Peter Tamm was the former chairman of the Axel Springer AG, which is one of the largest multimedia companies in Europe. Together with the local government Peter Tamm decided to transform the warehouse to show his private collection to the public. The exhibition items are displayed on a total area of 12.000 m2, and vary from dugout maritime archaeological findings, to models, uniforms and construction plans. The museum has ten floors, with each another maritime related subject. The museum attracts around 150.000 visitors per year.

The group started on the top floor and slowly walked their way down while looking at the exhibited items. Our group spent most of the time on the floors with naval ships and the developments of ships and engines. The models were made even more interesting by the discussions of the group, triggered by stories of group members with personal connections to the Dutch Navy.

In front of the building there was a rather large ship propeller which was donated to the museum by our of the tour’s sponsors; Wärtsilä. After finding out the propeller was cast in Drunen in The Netherlands, the group decided to make a picture with the Dutch piece of workmanship. Unfortunately the casting facility has since disappeared although an office of Wärtsilä still remains at that location.

The Hamburg maritime museum was a nice side trip; especially the discussions within the group will leave knowledge and ideas that will stick around and gives a historical perspective to our field of study. Written by: Maarten Sanders

Thursday: Lürssen Yachts For a change, the van arrived before the car, giving the passengers some time to relax and meet with out contact and guide Mr. Breman, sales director at Lürssen Yachts. When the car arrived we expected to receive the usual company presentation but instead Mr. Breman announced that we should step back into our vehicles and follow him to the yards and engineering offices on the other side of the river.

The first step of this tour was a visit to Lürssens largest dock, where just outside lay their latest superyacht Azzam in the final stages before delivery. Although Lürssen builds superyachts, the Azzam stretches the definition of ‘super’. This 180 meter long ship is powered by two turbine engines making her capable of reaching speeds in excess of 30 knots. Since the delivery a mere couple of months after our visit she is officially the largest yacht in the world.

After learning about the unique demands for customers of different origins (apparently Americans like a bar on every deck and Arabs never ask for a swimming pool) we again reached out to our tiny transportation and drive to the other facilities and offices. Lürssens facilities are bigger and spread around quite a lot more than we anticipated. The next stop was a look at the engineering offices, a first for this studytour. The chief engineer guided us through the design process using blueprints of Lürssen yachts while around us engineers were hard at work with CAD software on structures, piping, electrical systems and climate control. Perhaps this is the future workplace of one of our students?

That it is possible for a Dutchman to start a successful career in Germany is proven by Mr. Breman. Originally of Dutch origin he moved to Germany, citing amongst other reasons the German spirit of doing things properly. During the kindly provided lunch his stories and sense of humour kept us entertained. Apparently Lürssen has remained a family-run German shipyard since its inception in 1875 and is now in its fourth generation of private ownership. The company was founded by Friedrich Lürssen with a desire to create a leading shipyard in both quality and performance. Lürssen Yachts focuses on the larger ships compared to their competitors in Germany or The Netherlands.

After the nice lunch in the company canteen we continued our tour across the facilities where unique features were the highly labour intensive and skilled sheetworking and the jet thruster on the bow of a new yacht in drydock.

Unfortunately all good things come to an end and this includes the final company visit of the study tour. After receiving a very weighty bag with illustrated books of Lürssen yachts and other goodies

VST2013 Page 17

Vulcanus Studytour 2013 we thanked Mr. Breman and his collegues for his informative tour filled with humorous storytelling and set off back to Delft. Minus one of our students who was kindly offered a ride to the train station.

Thursday: Return to Delft: After all of the excursions and the nice city of Hamburg it was unfortunately time to go home again. The drive to Delft went smooth again, but due to an error of the driver we almost ended up in Amsterdam. Luckily this didn’t happen. Because it was late when we arrived, the Board decided to take us to a Burger King, where we all reminisced about the things we’d seen and done during this wonderful trip.
